Hi John,
Somehow, we will manage to post something about the trip, if not live on board, then a short trip report afterward. We used guides mostly from the private guides section of the board.
The guide in Monte Carlo was busy, so I suggest you book now. We have a 1/2 day in Lisbon, Santander, Malaga, Bordeaux all booked for private tours. In Honfleur, we think we're walking around the town or catching a taxi from the dock to not sure where yet. And in London, we're putting on our walking shoes and just going!
